About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
Degenerate distribution constructor.
import Degenerate from 'https://cdn.jsdelivr.net/gh/stdlib-js/stats-base-dists-degenerate-ctor@esm/index.mjs';
Returns a Degenerate distribution object.
var degenerate = new Degenerate();
var mean = degenerate.mean;
// returns 0.0
By default, mu = 0.0
. To create a distribution having a different mean value mu
, provide a parameter value.
var degenerate = new Degenerate( 20.0 );
var mean = degenerate.mean;
// returns 20.0
A Degenerate distribution object has the following properties and methods...
Constant value of the distribution.
var degenerate = new Degenerate( 2.0 );
var mu = degenerate.mu;
// returns 2.0
degenerate.mu = -2.0;
mu = degenerate.mu;
// returns -2.0
Returns the differential entropy.
var degenerate = new Degenerate( 4.0 );
var entropy = degenerate.entropy;
// returns 0.0
Returns the mean.
var degenerate = new Degenerate( 10.0 );
var mu = degenerate.mean;
// returns 10.0
Returns the median.
var degenerate = new Degenerate( 10.0 );
var median = degenerate.median;
// returns 10.0
Returns the mode.
var degenerate = new Degenerate( 10.0 );
var mode = degenerate.mode;
// returns 10.0
Returns the standard deviation.
var degenerate = new Degenerate( 4.0 );
var s = degenerate.stdev;
// returns 0.0
Returns the variance.
var degenerate = new Degenerate( 4.0 );
var s2 = degenerate.variance;
// returns 0.0
Evaluates the cumulative distribution function (CDF).
var degenerate = new Degenerate( 0.2 );
var y = degenerate.cdf( 0.5 );
// returns 1.0
Evaluates the natural logarithm of the cumulative distribution function (logCDF).
var degenerate = new Degenerate( 0.2 );
var y = degenerate.logcdf( 0.5 );
// returns 0.0
Evaluates the natural logarithm of the probability density function (logPDF).
var degenerate = new Degenerate( 10.0 );
var y = degenerate.logpdf( 9.0 );
// returns -Infinity
y = degenerate.logpdf( 10.0 );
// returns Infinity
Evaluates the natural logarithm of the probability mass function (logPMF).
var degenerate = new Degenerate( 10.0 );
var y = degenerate.logpmf( 9.0 );
// returns -Infinity
y = degenerate.logpmf( 10.0 );
// returns 0.0
Evaluates the moment-generating function (MGF).
var degenerate = new Degenerate( 10.0 );
var y = degenerate.mgf( 0.1 );
// returns ~2.718
Evaluates the probability density function (PDF).
var degenerate = new Degenerate( 10.0 );
var y = degenerate.pdf( 2.0 );
// returns 0.0
y = degenerate.pdf( 10.0 );
// returns +Infinity
Evaluates the probability mass function (PMF).
var degenerate = new Degenerate( 10.0 );
var y = degenerate.pmf( 2.0 );
// returns 0.0
y = degenerate.pmf( 10.0 );
// returns 1.0
Evaluates the quantile function at probability p
.
var degenerate = new Degenerate( 10.0 );
var y = degenerate.quantile( 0.5 );
// returns 10.0
y = degenerate.quantile( 0.9 );
// returns 10.0
